If you don't wish to give your bank details to someone paying you via TransferWise, you can now nominate a primary account for the currency you want to receive.
You simply need to go to your 'Recipients' page from the menu to the left, where you'll see all your recipient accounts. If you haven't previously sent money to yourself in another currency, you can add your account by clicking 'Add new' next to 'My bank accounts'.
Once you've added your account, you can click on 'Mark as primary account to receive XXX' (This will be the relevant currency to that account, e.g. EUR, GBP, CHF etc).
Please note that if you are sending from AUD or USD, you will not be able to choose to send a transfer to a Primary Account unless the address has also been entered.
